MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA- TION OFPENNSYLVANIA WINDOW SHADE Application filed November 24, 1928. SerialNo. 321,716.

My invention relates to certain improvements in window shade -fabricsWhichare ap lied to spring-rollers.

no object of my invention is to insure the proper alignment of thefabric with the roller when the fabric is secured to the roller, so thatthe window shade will be parallel with the sides of the window'frame.

A further object of the invention is to provide the fabric with meansfor securing said fabric to the shade roller without the use of tacks orother metallic fastenings.

These ob'ects' I attain in the following manner, re erence being had tothe accompanying drawing, in which:

ig. 1 is a perspective view of a window shade roller, showing alongitudinal indicating mark with which the 'window shade is aligned;

Fig. 2 is a perspective view of the upper end of a window shade,showinga longitudinal line on the shade and. perforations through which thelongitudinal line on the roller can be sighted; and

Fig. 3 is a face view of a portion of a window shade applied to aroller.

Referring to the drawing, 1' is a springroller, of any type, havingtrunnions 22, one at each end. In the ordinary roller, one so of thesetrunnions is attached to a spring and suitable ratchet mechanism isused.

w is a longitudinal line, extending parallel with the centre line of theroller, w1th which 'the shade must be aligned in order to roll perfectlystraight. This line or marking, which may be made in any suitablemanner, .extends from one end of the roller to the other. I The windowshade 3' is made of any suit- 40 able fabric, the word fabric being usedin its broadest sense to gover paper or woven fabric, and in order toattach the window shade to the roller, a securing strip 4 is used. Thesecuring strip 4 is of woven fabric and has an adhesive coating 5 on theback thereof, as shown in Fig. 2, which figure illustrates a portion ofthe securing strip turned up. The adhesive coating is moistened andapplied to one end of the window shade as shown, and the window shade issold With the securing strip attached thereto. i

In order that the window shade 3 may be properly secured to the windowshade roll-- er 1, a longitudinal line a is printed on the face of thesecuring strip in any suitable manner, and at intervals the securingstrip is perforated, the perforations I) being made in the centre, sothat the line a will pass directly through the centre of theperforations, as shown in Fig. 2.

To apply the window shade to the roller, the back of the securing stripis moistened and the strip is laid upon the roller With the lines a anda: in alignment.

In order to allow the person applying the shade to the roller to readilysee if the two lines are in perfect alignment, the line :2 on the rollerwill be visible through the perforations b in the securing strip, asclearly illustrated in Fig. 3. When the two lines are in exactalignment, then the moist portion of the securing strip is pressed downupon the roller until the adhesive material attaches the strip and itsshade to the roller, after which the shade roller can be mounted in itsbrackets on the window frame, and if the I brackets are in properalignment, then the window shade Will be parallel with the sides of thewindow frame.

In some instances, the end of the fabric maybe provided with adhesiveinaterial and the fabric near one edge may be perforated and lined,dispensing with the securing strip.

I claim 1. The combination of a window shade roller having alongitudinal line extending parallel with the center line of said rollerand a window shade having a series of perforations in its upper edge ofsuch size that the longitudinal line of the said roller can be seenthrou h the perforations of the window shade and showing the properalignment of the window shade with the roller when 7 the shade issecured to said roller.

2. The combination of a window shade roller having a longitudinal lineextending parallel with the center line of the roller and a window shadehaving a securin strip attached thereto, said securing strip aving m aseries of perforations arranged on a line at right angles with the sidesof the window shade so that when the window shade is applied to theroller, the longitudinal line of the window shade will be exposedthrough 15 the perforations in mounting the shade on the roller. Y

3. The combination of a window shade roller having a longitudinal lineextending parallel wtih the center line of said roller and 20 awindowshade having a line at its upper edge at right angles to the sideof the window shade and a series of perforations in said window shade,said line of the window shade I extending through the perforations sothat I g when the shade is applied to the roller, the

line on the window shade can be brought into alignment with the line onthe roller.
